Variable | OR | 95% CI | p value |
APACHE II (points) | 1.189 | 1.071 to 1.319 | 0.001 |
AKI (%) | 23.784 | 6.129 to 92.296 | <0.001 |
RDW (%) | 1.401 | 1.156 to 1.697 | 0.001 |
Note, variables in the model included age, haemoglobin, mean corpuscular volume, haematocrit, APACHE II score, AKI, TLSH, gestational age and RDW.
Due to the high correlation between haemoglobin and haematocrit, haemoglobin was first regressed on haematocrit.
AKI, acute kidney injury; then placed the residual and haematocrit in the multivariate regression. APACHE II score, Acute Physiology and Chronic Health Evaluation II score; RDW, red cell distribution width.
